WHEEL CLEANING ATTACHMENT FOR TRACTORS- Filed Nov 7. 192'? Patented June 17, 1930 UNITED STATES GUY BABY, OF VERMONT, ILLINOIS WHEEL-CLEANING ATTACHMENT FOR TRACTORS Application filed November This invention relates to a wheel scraping attachment designed primarily for use in connection with tractors, one of the objects being to provide a simple and efficient device of this character which is cheap to manufacture and which can be applied readily to a tractor without requiring the services of a skilled mechanic.

A further object is to provide a device is formed of the minimum number of parts capable of withstanding rough usage and operating efiiciently under all conditions.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawing, which is a perspective view, the attachment has been shown applied to a tractor a portion of which has been illustrated.

Referring to the drawing by characters of reference 1 designates brackets having inte ral sleeves 2 which are split transversely 39 as indicated at 3 for the reception of collars 4 carried by a transverse shaft 5. These col lars are held against longitudinal movement relative to the shaft by means of set screws 6 and constitute means for holding the shaft against longitudinal displacement relative to the sleeves 2. The ends of the shaft project laterally beyond the sleeves and mounted on them are sleeves 7 each having an integral blade 8 projecting therefrom. Set screws 9 49 or the like are employed for holding the sleeves 7 against movement relative to the shaft 5. The blades are so proportioned and located as to extend between the cleats C on the wheels W of the tractor. An arm 10 is extended from the shaft 5 and has a coiled spring 11 attached to the free end portion thereof, this spring being extended under the shaft 5 and connected to a portion of the tractor so as to be normally under tension. 53 Brackets 1 can also be attached to any desired 7, 1927. Serial No. 231,596.

portions of the tractor, such as the fenders F.

In using the device the brackets are secured in place and the spring 11 is also attachedto the tractor. The sleeves 7 are adjusted along the shaft 5 so as to bring the blades 8 to positions where they will work bet-ween the cleats C. The pull of the spring 11 on the arm 10 will cause these blades to bear firmly against the peripheries of the wheels. The blades will incline upwardly and rearwardly relative to the wheels and it will be apparent that, when these wheels rotate, the said blades will act to wedge back of accumulations of soil carried by the rims of the wheels and push them backwardly off of the cleats so as to leave the cleats practically clear and maintain them at maximum efiiciency.

What is claimed is:

A wheel cleaning attachment for-tractors including attaching brackets for engagement with opposed fenders of a tractor, spaced integral sleeves extending from each bracket, a rock shaft journaled in all of the sleeves and adapted to extend transversely of a tractor, collars adjustably mounted on the shaft and interposed between the sleeves on each bracket, thereby to hold the shaft against longitudinal movement relative to the. brackets, said brackets and collars being adjustable along the shaft for positioning the brackets on fenders at different distances apart, scraping blades, a sleeve on one end of each blade into which one end of the shaft projects, means carried by the sleeve for binding it on the shaft, thereby to insure rotation of the blade with the shaft, said blades being adjustable toward and from each other on the shaft, an arm radiating from the shaft, and a spring for connecting the arm to a portion of a tractor thereby to hold the blades pressed yieldingly against the periphery of the tractor wheels.

In testimony that I claim the foregoing as my own, I have hereto afliXed my signature.

GUY RABY.
